Une faille entre les dimensions et voilà que ceux qui n'aurait jamais dû se rencontrer se trouve face à face. (Swap Papyrus X Fell Sans)

Après sa mort, Frisk reviens sous forme de squelette et vie parmi les Monstre. Malheureusement (ou heureusement), il a tout oublié de sa vie d'humain... [Petite Fic de Noël]

"Hey guys, it's me Aquadearest, but you may call me Aqua."(Aquadearest) "And my name is Lonewolf. I'm just here cause Aqua's here."(Lonewolf) "Lighten up, Wolfy, This is fun! Feel free to check out anything you want!"(Aquadearest) "But DON'T call me Wolfy. Only Aqua calls me that."(Lonewolf) "Have fun, people and thanks for stopping by!"(Aquadearest)

It was kind of stupid, if you ask him. Ask him about his past and he won't answer. Or more like can't answer. Sans looses his memory during a genocide run. When he wakes up, he finds himself in a new place with new friends, enemies and a new name.

"I WOULD NEVER TAKE A VACATION FOR ANY REASON," claims Papyrus. He's taking one now.

You are a mage, part of a secret underworld lost to time that is slowly disappearing. Every mages' powers manifest differently, and yours are like something taken straight from a video game. After a few years, that's how you start to see your life, as one big game. That all changes though when the days start to repeat themselves and your the only one aware of it. AU Crossovers.

Frisk is unable to let go of the past. He's freed the monsters from the Underground, but there's still those who could not be saved. When his past catches up, he's left wondering about his life, and it spirals into a pit of depression and hopelessness. Deciding there is nothing's left to lose, Frisk sets out to Mt. Ebott. Everyone deserves a second chance, no matter the cost.

A short crossover where Asriel Dreemurr, the God of Hyperdeath, fights a 7-chaos emerald powered Mecha Sonic. Takes place during the Super Mario Bros Z series.

Frisk is near the end of a genocide run, but King Asgore won't go down without a fight. But can he stop the human's reign of terror? Does it even matter at this point? Unrelated to my other fic, DarknessTale. I made this because I've always thought a genocide Asgore fight would be an interesting "what if."

Every year, there is always a gift for fourteen year old Papyrus from Santa under the Gyftmas tree. But Sans never has one, which Papyrus doesn't feel is fair. His big brother deserves all the gifts in the world! And after he discovers his Santa is actually Sans, he decides his beloved brother deserves a Santa of his own.

Many monsters are due for a celebration, and this one seems like it might end up taking the cake.

Sans is being such a jerk, but why?

Will they truly enjoy their time together? Rated T for safety.

A Cindallas Chronicles AU

Who we are inside and outside, are often different. How others see us, and how we see ourselves, can be total opposites, and yet they are linked. A small child fell into the Underground, but, by the Power inside, nothing will ever be the same... "Courage of the Heart is very rare, but it has Power, when it's there."

In which Frisk is given a gift, one that she will definitely keep for as long as she can. [Frisk & Patience Soul, double drabble]
